Chrysanthemum plant named `Party Time`

ABSTRACT

A new plant variety of Chrysanthemum producing white flowers.

BACKGROUND OF THE INVENTION

The present invention is directed to a new and distinct variety ofChrysanthemum botanically classified as Dendranthema grandiflora. Thevarietal denomination of the new chrysanthemum is `Party Time`.

The female parent of the new variety is an undistributed, unpatentedseedling identified as p 79-5 and the male parent is the variety knownas `Fashion Time` (U.S. Plant Pat. No. 9,935). The new variety has beenasexually reproduced by vegetative cuttings in Ventura County, Calif.and the distinguishing characteristics are retained through successivegenerations of asexual reproduction.

SUMMARY OF THE INVENTION

`Party Time` is a pot forcing chrysanthemum plant variety that produceswhite flowers and dark green foliage and has a flat capitulum form andflower size of about 9 cm across.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph shows a typical specimen of the new varietywith colors being as nearly true as possible with illustrations of thistype.

DESCRIPTION OF THE PLANT

The following description of the new variety is of specimens grown in agreenhouse in Ventura County, Calif. in the month of October. `PartyTime` has not been observed under all possible environmental conditions.The phenotype may vary with variations in the environment such astemperature, light intensity, day length and cultural conditions. Thecolor description is by reference to The Royal Horticultural SocietyColour Chart.

Plants of the new variety have been grown successfully in a greenhouseunder temperature conditions averaging about 65° F. at night and about75 -85° F. during the day under light conditions of about 5,000-6,000foot candles. To produce a commercial product the plants may be pinchedonce center bud removed. It has been observed that the shelf life of`Party Time` is about 29 days with the response time of about 9 weeks.
